FLY-TRAP.

Specification of Letters Patent.

Patented Dec. 31, 1918.

Application filed January 25. 1917. Serial No. 144.428.

To allwhom it may concern: I

Beit known that I, Ann-ion C. LA MAY, a citizen of the United States, residing at Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Fly-Traps, of which the following is a specification.

The object of this invention is to make a new and improved form of a fly trap.

This and other objects of the invention will be .fully illustrated in the drawings, described in the specification and pointed out in the claims at the end thereof. In the drawings,

. Figure 1 is a side elevation of iny improved trap. I

.Fig. 2 isan end elevation of my improved trap. V

Fig. 3 is a vertical section on the line of Fig. 1.

Fig. 4 is a longitudinal'vertical section on the line 1"4" of Fig. 2.

. Fig. 5 is a top plan view of the base.

In the drawings like reference numerals indicate like parts. I

In the drawings reference numeral 1 indirates the base which is composed of a single sheet of metal having a longitudinal depression 2 formed therein forming a trough for holding the bait of the trap. The sides ofthe base are'depressed as indicated at 3 and't to form a runway for flies- Between the runway and the trough are formed the ridges 5 and 6 Which extend. nearly the whole length of the base. At each end of the base these ridges 5. and 6 flare outwardly and form the platforms 7 and ,8 on which the trap itself is supported. In each of these platforms are formed the slots 9 and 10.

In these slots are mounted the upright plates 11 and 12 which form the ends of the trap. Each of these plates has a flange formed thereon as indicated at 18 and 14. Each of these flanges extends down to and engages with and rests on the platforms 7 and 8. The plates 11 and 12 extend below the flanges as indicated at 15 and 16. The bottom part of the plates pass through the slots 9 and 10 as indicated in cross section in Fig. 4. These plates can be readily removed from the base and inserted in place thereon.

Each of the ends of the trap is provided with a longitudinal opening as indicated at 17 in Fig. 3, the metal surrounding this opening being depressed as shown in Fig. 4.

Between the ends and connecting them together is placed a rod 18 having eyes 19 on each end thereof, which eyes pass through the slot, 17 after which the rod can be given a quarter turn which will make the eyes engage with the end and hold the ends together. .The round depression surrounding each of the openings 17 causes the eye to center itself in the depression.

Between the ends is placed the screen of the'trap, which screen will now be described.

The screen is composed of two sections,

the outer one of which, indicated bythe numeral 20, is horse shoe or tunnel. shaped conforming to the outline of the flanges on the ends and engaging within said flanges. The inner section is" wedge shaped and the lower edges of both sections come together and may be joined together in any suitable manner, the sections as shown being made sepalately and joined together at the bottom by a thin S-shaped strip of metal 22 which en-' gages the two ends and holds them firmly together. The top of the inner section is provided with the openings 21, 21 therein which are large enough to'let a fly pass therethrough. The ends of the joints between the two wire screen sections of the trap rest upon the ends of the platforms 7 and 8 and extend over the runways between them thus leaving a clearance between the bottom of the wire screen sections of the trap and the runways, so that flies can pass up between the bottom of the screen and the runway. The flies will walk up the runway until they reach the feeding trough after which they will fly or crawl up until they reach the openings 21 and pass therethrough into the space inclosed between the screen.

The trough in the base will be baited with any suitable bait such as stale ale or bread and milk, etc.

The trap is assembled by first placing the .screen section in place between the ends of the trap with the outer screen contained within the flanges on the ends after which the ends are inserted in place on the base. The ends can be locked together either before or after this by means of the rod 18. By reversing this procedure the trap can be as easily taken apart and cleaned.

I claim.

1. A base for a fly trap made rectangular in form having its middle portion elevated and having a long, narrow trough formed therein, a narrow ridge surrounding said trough, the sides of said base sloping upwardly from the edges of the base to said ridge and forming runways thereto, a screen supported on said base, said screen having ends that extend into the base, flanges on said ends above the base,'forming shoulders that rest on the elevated surface of said base and support said ends thereon.

2. A base for a fly trap made rectangular in form having its middle portion elevated and having a long, narrow trough formed therein, a narrow ridge surrounding said trough, the sides of said base sloping upwardly from the edges of the base to said ridge and forming runways thereto, said ridge being expanded outwardly at each end of the trough and transversely thereto, forming an I shaped surface, a screen supported on said base, said screen having ends that extend into the base, flanges on said ends above the base, formingshoulders that rest on the elevated surface of said base and support said ends thereon.

3. A base for a fly trap made rectangular in form having its middle portion elevated and having a long, narrow trough formed therein, anarrow ridge surrounding said trough, the sides of said base sloping upwardly from the edges of the base to said ridge and forming runways thereto, said ridge being expanded outwardly at each end of the trough and transversely thereto, forming an I shaped surface, a slot in each of said expanded portions of the ridge extending transversely to said trough, a screen sup ported on said base, said screen having ends that extend into the base, flanges on said ends above the base, forming shoulders that rest on the elevated surface of said base and support said ends thereon.

4. A base for a fly trap made rectangular in form having its middle portion elevated and having a long, narrow trough formed therein, a narrow ridge surrounding said trough, the sides of said base sloping upwardly from the edges of the base to said ridge and forming runways thereto, said Copies of this patent may be obtained for ridge being expanded outwardly at each end of the trough and transversely thereto,

forming an I shaped elevated surface, a slot in each of said expanded portions of the ridge extending transversely to said trough, an upright plate reniovably engaging each slot, each of said plates having a flange on the edge thereof above the base and resting on the base, a screen extending between said end plates and held in place by the flanges thereon, an inner screen extending upwardly from the lower edges of said screen and having enlarged openings at the top edge thereof, said inner screen being located above the open top of said trough and part of said runways, and means for holding said ends together.

5. A base for a fly trap made rectangular in form having its middle portion elevated and having a long, narrow trough formed therein, a narrow ridge surrounding said trough, the sides of said base sloping upwardly from the edges of the base to said ridge and forming runways thereto, said ridge being expanded outwardly at eachend of the trough and transversely thereto, forming an I shaped elevated surface, a slot in each of said expanded portions of the ridge extending transversely to said trough, an upright plate removably engaging each slot, each of said plates having a flange on the edge thereof above the base and resting on the base, a screen. extending between said end plates and held in place by the flanges thereon, an inner screen extending upwardly from the lower edges of the said screen and having enlarged openings at the top edge thereof, said inner screen being located above the open top of said trough and part of said runways, means for holding said ends together, the lower edges of said screens being held together over the sloping sides of the base leaving runways below them.
